i can tell you jamal now has 3 cookies xd

tommy has 2.

this made me lol.

explanation:

infrared radiation has wavelength in the range between 700 nm and 1 mm. lets' convert these values into scientific notation, keeping in mind that:

let's start from the lower value, we have:

(we moved the dot two places to the left, so we increased the exponent by 2 units, from -9 to -7)

the higher value is:

so, the range of wavelength of infrared radiation is:

the equation is not included but the answer is (1.50, 2.00, 2.75)
